Z86 Type Filler CAS 61790‑53‑2 is high‑purity fine‑milled natural siliceous earth filler with unique porous particle morphology. As rheology‑adjusting functional extender for sealant and adhesive, it builds stable thixotropic network inside system, effectively resists sagging and vertical flow during construction. Besides rheology improvement, it enhances tensile strength, hardness and dimensional stability of cured sealant, widely suitable for silicone, PU, MS hybrid polymer and other adhesive‑

Product Detail

Overview

Our Z86 Type Filler CAS 61790‑53‑2 is refined from premium diatomite ore through purification, ultra‑fine grinding and strict particle‑size screening. This grade is purpose‑developed as rheology modifier for sealant and adhesive industry. It cooperates with fumed silica and other thixotropic agents to optimize paste property, reduce formula cost while guaranteeing anti‑sag performance and final cured mechanical performance of sealant and adhesive.

Key Features

Produce stable thixotropic effect, greatly improve anti‑sagging and non‑slump property for vertical‑surface construction.
Enhance hardness, tensile strength and tear resistance of cured sealant and adhesive.
Reduce shrinkage ratio after curing, improve dimensional stability of sealant bead.
Good compatibility with silicone, polyurethane, MS polymer, polysulfide and most adhesive‑sealant resin systems.
Optimize extrusion performance of cartridge‑packaged sealant, smooth discharging without grainy feeling.
Low soluble impurity content, less interference to curing catalyst system, stable shelf life of finished products.

Main Applications

Silicone sealant, neutral and acid silicone adhesive
Polyurethane PU sealant and adhesive
MS hybrid polymer sealant
Construction joint sealant, industrial assembly adhesive
Various paste‑type sealants requiring anti‑sag and rheology control

Usage Recommendation

Typical dosage range: 8‑25% by weight, adjust according to target thixotropy, extrusion force and mechanical requirement.
Add in planetary mixer or kneader, ensure sufficient mixing and wetting with resin phase.
Raw material must be fully dried before feeding; high moisture will interfere curing effect of sealant.
Can be used together with fumed silica, calcium carbonate to realize formula cost balance.
Complete lab test on extrusion property, sag resistance, curing speed and mechanical data before mass production.

Storage & Package

Store in dry and dust‑proof warehouse, keep bags tightly sealed to avoid moisture ingress.
Standard package: 25kg woven bag with inner PE liner.
